Part 1: Examing the dataset

Part 2: Exploration

Part 3: Research question

-> Are herbivores longer than carnivores on average?

μ1 -> herbivore mean

μ2 -> carnivore mean

H0: μ1 ≤ μ2

Ha: μ1 > μ2

Selected confidence interval = 95%

Since P(Z > 12.38) < 0.05

We reject the null.

This means that herbivores are on average larger than carnivores.
